[0002] As a pollution-free and environmentally friendly means of transportation, trams are rapidly developing in major cities, but the operation of trams has the following disadvantages: 1. It shares intersections with public transportation. 2. It is easily disturbed by external factors during operation.
In order to improve the speed and operational efficiency of trams passing through intersections, most tram lines in China currently adopt the intersection priority method. Due to the lack of accurate calculation and analysis in the early stage, after the line is opened, many trams have achieved priority At the intersection, the service level of the road where the tram line is located and the traffic capacity of social vehicles are reduced, resulting in traffic congestion at the intersection; if the priority of the tram intersection is cancelled, it will affect the operation efficiency and service level of the tram

The present invention provides a simulation method for a priority mode of a tramcar. The method comprises the following steps: acquiring a road model of an operation line of the tramcar; drawing a line map consistent with the road surface condition of the operation line according to the road model; acquiring operation parameters of the tramcar; acquiring relevant parameters of the operation line;according to the operation parameters of the tramcar and the relevant parameters of the operation line, by combining with the priority mode, performing simulation operation of the tramcar on the operation line; saving simulation data generated during the simulation operation; and determining whether a pause signal is received, if so, suspending the simulation, and outputting a simulation report summarized according to the simulation data and the road traffic flow parameters, and if not, continuing to perform simulation. According to the technical scheme of the present invention, after performing simulation on parameters of the tramcar and of the operation line, a reasonable intersection priority mode is obtained, and technical support can be provided for the construction of the tramcar.
